256 Core Fiber Optic Joint Box

256 Core Fiber Optic Joint Box

 

 

It is a universal access junction box that allows the continuity and segregation of medium capacity optical cables used in the deployment of optical power and transport networks.

The design of the box allows the mechanical continuity of the tensile elements of the cables and protects the fibers, the unions, and the optical devices facilitating the organization of the splices and the storage of the fiber excess.

The box is airtight and resistant to outdoor conditions so it can be installed both outside and inside buildings in log houses, manholes, walls, poles, or cable galleries

 

It has 4 independent cable accesses at one end. Each of them allows the individualized entry of at least two medium capacity multifiber cables (double inputs) and up to 6 small capacity optical cables (7mm)

 

The closing lid is completely assembled and removed without the need for special tools thanks to the clip-type hermetic seal.

 

The sealing of access cables to the box is made by rubber gaskets with pre-cut entries.

 

Diameter inputs / outputs cables from 22 to 7 mm. Maximum 256 fusions of F.O (double layer).

 

Rectangular, wide-reach, easy-access splice trays with extendable tabs for better fiber storage up to 32 F.O. (double layer). Both the support block and the individual trays allow the rotation to 90º and its interlocking in fixed positions to facilitate installation.

 

The boxes can be opened, closed and manipulated without interrupting the circuits in operation. It allows to join and segregate cables without having to cut all the fibers as well as the adequate storage of the tubes and / or fibers left over from the cables.
